At the Battle of Lumphanan, King Macbeth of Scotland is slain by Malcolm Canmore, whose father, King Duncan I, was murdered by Macbeth 17 years earlier.
Macbeth was a grandson of King Kenneth II and also had a claim to the throne through his wife, Gruoch, who was the granddaughter of Kenneth III—the Scottish king who had been overthrown by Duncan’s predecessor King Malcolm II. Under King Duncan, Macbeth was governor of the Scottish province of Moray and a trusted military commander. However, he opposed Duncan’s ties to the Saxons in the South, and he rose in rebellion. On August 14, 1040, Macbeth killed Duncan in a battle near Elgin, and he was crowned king of Scotland in his place.
In 1054, after 14 years of rule, King Macbeth suffered a major military defeat at the Battle of Dunsinane against Siward, the earl of Northumbria. Siward was acting on behalf of Malcolm Canmore, Duncan’s son. Malcolm then gained control of the southern part of Scotland and spent the next three years pursuing Macbeth, who fled to the north. On August 15, 1057, Macbeth was defeated and killed by Malcolm at the Battle of Lumphanan with the assistance of the English. Malcolm Canmore was crowned Malcolm III in 1058.
